In protrusive jaw relation, the mandible moves anteriorly, causing disocclusion of the posterior teeth as the mandibular anterior edges glide against the maxillary anterior surfaces.

Lateral mandibular relation refers to the side-to-side movement of the mandible; the working side is the direction the mandible moves towards, while the nonworking side is the opposite side.

Canine-protected articulation results in disocclusion of the posterior teeth due to the vertical overlap of the maxillary and mandibular canines during lateral movements.

<p>Group function occurs when multiple teeth on the working side contact evenly during lateral excursions, aiding in stable occlusal relationships, particularly in complete dentures.</p> Signup and view all the answers

<p>The Curve of Spee is the upward curve formed by the incisal and cusp edges of teeth from anterior to posterior when viewed laterally, influencing tooth contact during occlusion.</p> Signup and view all the answers

<p>Bennett’s movement involves minimal lateral movement of the working condyle, which rotates and moves laterally only 1 to 2 mm during lateral excursion.</p> Signup and view all the answers

<p>Bilateral balanced occlusion allows all posterior teeth on the working side and one or more on the balancing side to contact simultaneously, which is beneficial for complete dentures to prevent tipping.</p> Signup and view all the answers

<p>In Class II malocclusion, the mandibular teeth are positioned distally to their normal maxillary counterparts, whereas in Class I, the mesiobuccal cusp of the maxillary first molar aligns directly over the mandibular first molar.</p> Signup and view all the answers
